- Patients must be told to undertake lifelong ART.
- Start treatment for symptomatic patients regardless of CD4 cell count.
- Start drugs for asymptomatic individuals with CD4 cell counts <500/L.
- Do risk reduction counseling at each patient�clinician interaction.
- Regimen: Consider resistance�testing results and predicted virologic efficacy, toxicity and tolerability, pill burden, dosing frequency, drug�drug interactions, comorbidities, patient and practitioner preference, and cost and affordability.
- Combine two nucleoside reverse transcriptase inhibitors and a potent third agent from another class.
- Prefer a fixed�dose formulations and once�daily regimen.
- Suppress HIV to less than 50 copies/mL (polymerase chain reaction) or 75 copies/μL (branched DNA) by 24 weeks.
- To detect Failure: repeat testing of HIV�1 RNA 2 to 8 weeks after initiation, every four to eight weeks until suppressed, and then every 3 to 4 months for at least the first year.
- Monitor CD4 cell counts at least every 3 to 4 months after starting therapy, especially in patients with counts <200/μL, to assess whether prophylaxis is needed for opportunistic infections.
- Do more frequent monitoring in patients who have changed therapy because of virologic failure.
- Even if one or more regimens have failed, the therapeutic goal should still be undetectable plasma HIV�1 RNA levels.
- Achieve this goal with new drugs and regimens.
- If an elevation in viral load occurs after complete suppression is achieved, consider poor adherence, drug�drug interactions, concurrent infections and recent vaccinations as possible causes before changing regimens.
- Repeat testing for an isolated detectable viral load to exclude errors or self�resolving low�level viremia.
- When changing regimens after first� or multiple�regimen failure, consider the stage of HIV, nadir and current CD4 cell count, comorbidities, treatment history, current and previous drug resistance tests, and drug interactions.
- Include at least two drugs, and preferably three fully active drugs or drugs from new classes.
- Single�agent switches to decrease toxicity, avoid drug interactions, or improve convenience and adherence are possible, provided the potency of the regimen is maintained and drug interactions are managed.
- Boosted protease inhibitor monotherapy is not recommended, except when other drugs raise issues of toxicity or tolerability.
- Delaying such switches may affect adherence and risk development of resistance
